Abstract

Multiple shoot induction in Sapindus emarginatus vahl has been achieved by two methods: (1) Direct germination of Sapindus emarginatus. vahl seeds in 6-benzylaminopurine (3.0mg/ L) supplemented MS liquid medium and supported on a filter-paper bridge and (2) in planta treatment with 6-benzylaminopurine (100 μg on alternate days) of the axillary bud regions of plants germinated and maintained under sterile conditions. While the former method resulted in as many as 7.5±8.6 shoot buds from the cotyledonary node within four weeks, the latter yielded on average approximately 8 shoot buds from each treated node in eight weeks. The cytokinin treatment in planta consisted of placing sterile filter paper moistened with sterile distilled water over the node and adding different concentrations of 6-benzylaminopurine. The shoots elongated and rooted directly in vermiculite after a pulse treatment with IBA (2.5 mg mL-1) for 15 min. Fungus growth, a serious problem in Sapindus emarginatus. vahl tissue culture, was controlled using a fungicide, Bavistin, along with elimination of organic nutrients from the growth medium.
